Embodiment Construction

[0028] The invention provides a torsional vibration damping method of a transmission system, which mainly includes adding a torsional vibration damper in parallel to the transmission system to reduce vibration for a specific modal frequency in the torsional direction, the effect is remarkable, and the parallel form is not Changing the original transmission system structure can be used to repair abnormal vibration afterwards.

[0029] The mechanical principle of this technical solution is to tune the moment of inertia to reduce vibration, that is, to connect the tuned moment of inertia damper (including the moment of inertia block, spring and damping unit) to the transmission system, and to resonate the control mode shape of the moment of inertia block and the transmission system. The torsional vibration energy on the driveline is transferred to the tuned moment of inertia damper, which dampens the torsional vibration of the driveline.

[0030] Based on the above principles, th...

Abstract

The invention provides a transmission system torsional vibration reducing method and application thereof. The method is characterized in that a torsional vibration damper, which is a tuned rotary inertia damper, is added on a transmission shaft in a parallel connection manner, and the torsional rotation movement around the transmission shaft is used for reducing the vibration level of a certain first order torsional mode frequency. The method is flexible, can effectively reduce vibration without damage to the original structure of the transmission system, and can be used for later repair of the transmission system. The method can be applied to wind energy / tidal current energy generator sets; the torsional vibration damper is installed on a shaft, connected with a generator, of a high speed shaft coupler to greatly reduce a first-order mode component in the torsional vibration, so that a transmission system can operate more stably, the reliability of the structure can be improved and the service life can be prolonged.

Description

technical field [0001] The invention relates to the technical field of mechanical vibration reduction, in particular to a transmission system torsional vibration reduction method and application thereof. Background technique [0002] For wind turbines and tidal current energy generators with gearbox transmission, the torsional vibration of the transmission system is dominated by the first-order modal frequency. Significantly reducing the first-order modal component in torsional vibration will make the transmission system run more smoothly, and the torsional fatigue load of each component will be smaller, which will help improve the reliability and life of the structure. [0003] At present, in wind power generators and tidal current energy generators, vibration reduction in the form of gearbox vibration-damping supports is mostly used. The common technical solutions for reducing the torsional vibration of the transmission system in the automotive industry include the driven...
